Referring-more in detail to the drawings, my improved measuring device includes two chambers 1 and 2., which are mounted on :1 suitable frame WOTlL, indicated at 1 in the drawings. but which are entirely independcm of each other. Mounted above the chambers 1 and 2 are two glass tubes 18 and 19, which are associaied, respectively, with saicl. chambers. These glass tubes form sights. Said tubes are held against a lower bridge piece 7 soldered on the metal formihg the chambers by means of a cap 20, in which cap are arranged valves 21 and 22 of very small lift and apertures, such as at 23, which allow the air forced out. by one of the reservoirs (luring filling to flow into the adjacent e'esei'voir which is at this moment be.- ing discharged. Washers 8 may be retained in baskets and 25 opening at the lower part and having bearing slots in the upper part, which Washers by their number and volume enable a precise and definite volumetric rcgulaiion of the two measuring chambers and 2 to be efi'ected.

The "elves 21 and 22 liqui-s. when the chambers are filled. Any small quantity of liquid thrown out at the moment of release through the seats of the valves. 21 and 22 in a chambei' 27 the actuating means ancl'the overflow pipe 26 provides for the recovery of this liquid. It-

is excluded, however. from the measuring chamber and is not elelivered with the contents of the chamhez; A. small air admission valve 28 (see Fig. 2) allows external air to enter the chamber 27 and thus to pass into the measuring chambers, so as to rovide for the emptying of both chum ers when drawing oil the liquid. The liquid is drawn oil through an CXllQUSt pipe attached :0 the opening in the frame at 12. There is :1 discharge port 13, connected with the chamber 1, and this discharge port 13 extends lows lhrougzh the frame, and connects with a chamber 14 which leads 'to lhc'openiug 12 and the exhaust pipe connected therewith, There is also a discharge port 15 which connects with the chamber 2, and

which also extends down through the frame and connects with the chamber 14. These ports 13 and 15 have been referred to as discharge ports and they are discharge ports when the chambers 1 and 2 are emptying.

and the hole 23 is collected.

are closed by the I m seieess They are also filling ports when these chem hers ere filled. in other words, the lower enclot the port 13 is connectml to e cylindrical port 30 (see Figs. 1 and 8) which in tilt is connecteol to the port 10. On the other side of the valve casing, indicated at 31 in Fig. 3,'is e cylindrical port 32,,wliiclrlilre- Wise connects with the port 10. This sort 10 in turn connects with an opening in the casing, which is connected to a receiving or filling pipe. The valve 9, shown. in the drawing, is for the purpose of closing'tiie filling pipe when it is desired to measure less than ufull capacity of the measuring device. This is not a part of the present invention and further description thereof is not thought necessary.

The liquid 'fiows into the chamber 1 through the port 30, and the port 13, and

flows out of said chamber to the port 13 and chamber 14. A cylindrical valve 3, see Fig; 1, is adapted to fitinto the cylindrical port 30, and close the ports leading to'the filling pipe, or it into the chamber on the other side of the lower end of the port 13, and

close the outflow of the liquid from the chamber 1. Likewise, there is a cylindrical valve 3 which tits in the cylindrical port 32 and prevents the lll'ilOW to the chamber 2,

and likewise sits in a cylindrical opening at the lower end of the port which iestls to the clielnloer will prevents the outflow through the pipe 1..2. These two valves 3 anti 3 are mounted on the somestem, inclicetctl st in the drawings. When seioi stem is reciprocntecl the valves hemoved from a position WliBIfi theycut oi the filling of one chamber to a position where they will cut oil the filling of the other chamber, and during, this movement, when they cut oil a chamber from the filling pipe, they open said. chamber to the exhaust pipe; The valve stem 33 is connected to the lower cncl of s. lever 8, see Fig. l, which is pivotelly mountcrl st G on it bracket (3, carried by the frame oi the measuring apparatus. There is a second lever 53, preferably mounted on the same pivotal support (3. iispi'ing (3 is pivotelly connected at its-lower encl to the lever {3, adjacent its connection with the valve stem 32-3. and is connected at its upper elul at 16 to the upper end of the lever 5.

Between the ports lil and 15 the frame of the apparatus is provided with a cylindrical recessifi i. Located in this recess is u revers- 111g piston 4. Saul reversingpistoniis-cm awed by a stem 35 extending: out through the mil in the casing and suitl stein is connected to the lower end of the lever 5. The stem has n enlarged head 36. with a vertical slot in thicli the pin 37, carried by the lower end of the lever 5; enga 'es. The ports, as shown in Fig. l, are so positioned that the chiimber 1 is lillccl with liquid from the supply pipe. When the chamber is entirely tirely filled. This pressure on the liquicl will he transferred to the piston st and vill move seicl piston to the right, as viewed 1n Fig. 1. Such a movement or" the piston at will cause the lower end of the lever 5 to move to the other side of the pivot G -that is, take on sngulsr position. which is just the reverse of that shown in Fig. 1. As soon as this lever is on the other side of the in crum pivot 6, the spring is positioned so es to pull on the lower encl of the levcr wit; a pull which tends to swing the lever 6 the left, as vieweolin Fig. l, and this vrill shift the valves 3 and 3 on to the other valve seats. While this chamber 1 is being filled thechamberfi is emptying as the port- 32 is open. The shifting of the valve stem, however, through the actuation of the spring will connect the chamber 1 with the exhaust pipe and will. at the same time connect the chamber 2 to the filling pipe, so it is that thesechsmoersare alter nately connected with the filling and exhaust pipes. The spring moves the valve and is an'sctuflting mechanism for accomplishing this purpose. lhis spring, or octu sting mechanism formed thereby, is normally inactive, however." That is, when the pelts are in the position shown in .1 the spring: is on the right of the pivot 6*,

lit!

and, therefore, the lever cannot be further moved thereby. it has reached the extreme of its movement to the right. The actuating mechanism will stay thus inactive until this piston t moves the lever 5, so as to carry the uyper end thereof to the other side of the pivotal support 6 Then it is that the spring is so ositionetl as to move the valve in the opposite direction.

It will he noted, therefore, that l have here reversing valve mechanism .vhcrein valve is moved by an actuating mechanism. including a. spring, which is normally inactive, and the movement of: this spring; is initiated by the piston 4, which in turn is operated by the pressure on the fluid when the chz inhcr is full. I have, therefore, an actuating mechanism really to shift the valve, but which will not operate until the chamber is filled and enough pressure is put on to the fluid in the chamber to cause the controlling means to initiate the valve actuailing mechanism.

While I have shown a reversing valve wherein the valves are mounted both on the same stem, it will be understood, of course, that this mechanism may he modifiecl, the essential feature being that the controlling valves shall be simultaneously reversed so :is to connect alternately the measuring chemllll pressure when the chamber closes and is en;

the spirit of the invention as hers with the filling and the exhaust pipes, and that this valve mechanism shall be opfiifdtefil by an actuating means which is nor- ;irnally inactive, and wherein the controlling 'means is provided for initiating the movement of the reversing valves,

11; is obvious that minor changes in the detaib of construction, and arrangement of parts may he made without departing from so: forth in the appended claims. I
